Letters Patent No. 94,513, dated September 7, 1869; tmtedated August 27,1869.

IMPROVED BRICK-KILN.

The schedule referred to in these Letters Patent and making part of thesame.

To all whom it nury concern:

Be it known that I, J AMES V. B. Rmrsun, of the city and State of NewYork, have invented an Improvement in Kilns for Bricks, &c.; and dohereby declare the following to be a full, clear, and exact the'scription of the same, reference being bad to the anfor burning bricksin successive charges, in separate compartments, by one central tire, sothat one comparimcnt can be charged while another is being einptied, athird burned, and the others drying and becoming gradually heated.

By this construction it becomes unnecessary to extinguish the fire, andthe bricks are burned with greater uniformity than heretofore.

In the annexed drawing- (t represents a furnace of suitable size,located centrally between the diverging walls I) I), that run radiially,or nearly so, to the outer wall 0, in which" are openings or doorsleading to the various chambers formed as aforesaid.

Each chamber is roofed with an arch of brick or masonry, and between thefire-chamber a and the sur rounding chambers (I, fines c are introduced,and each is formed with a damper by means of which the heat may be shutoff from all the chambers except the one that is in use.

These flucs 0 pass into horizontal flues or arches, or a hollowperforated floor, upon which the bricks rest.

One of the chambers (f) is to be used for fuel and to give access to thefurnace a.

It will be understood that the combustion of the gases will be made asperfect as possible by the fireehamber being sufliciently large toretain them until proper combusition takes place, and that the brickswill be burned by the hcatet gases as in areverberatory furnace.

With this apparatus the chambers can be charged successively with thebricks and they become gradually heated by a small amount of gasesadmitted, and then the burning of each chamber, in its turn, iscompleted, after which the cooling and removal are in succession.

Coal may be employed. instead of the wood heretotofore used, therebycffcctinga saving in cost, and making a more uniform heat.

The central chimney 7:- may be employed to take away the waste productsof combustion, a series of openings or fines for that purpose beingprovided as at N, opening into a radial fine, m, that leads to thechimney. One of these fines may answer for two of the chambers (Z, anddampers should be provided to each of the tines l, or there may be afine, "m to each chamber. i

The main damper n allows the chimney h to be used in kindling the fire,or in case the heat becomes too great for any given chamber.

I prefer to have the fuel-opening of the furnace formed as shown forbanking in the coal, and an opening left at 1), allows the fire to beraked above the grate for drawing out cliukers.

This construction of kiln gives great facility for charging, heating,burning, and emptying the chambers successively, and I remark that theradial dividing-walls may be constructed with air-spaces or other meansfor preventing heat passing from one chamber to the other, and thearches and parts of the kiln may be tied or anchored in any desiredmanner to strengthen them.

The parts of the furnace exposed to high temperature should be linedwith lire bricks. V

The dampers should be made of fire-brick set in a clamp so that they canbe replaced, and the lcveis that work the respective dampers may all beconnected with pulls in the attendants compartment, f.

This kiln is particularly adapted to the burning of bricks, but I do notlimit its use in that particular, as it may be employed for otherarticles.

Openings and stoppers may be provided in the top of each chamber, forallowing the vapors to escape while drying and heating the brick, or toaid in cooling the kiln after the brick has been burned.

I do not claim a kiln with afire inthe cent-re, as in the Englishpatent, No. 1,582, A. D. 1865.

Vb-at I claim, and desire to secure by Letters Patcut, is-

The arrangement herein described, of a series of chambers around acentral fire, so that the operation of charging, burning, and removingthe bricks or other articles can be performed successively,substantially as specified.

In witness whereof, I have hereunto. set my signature, this 4th day ofJanuary, A. I). 1869.
